Description

For the first time, we created an air spring with a truly better spring rate, everywhere in the travel, than a coil. The Secus upgrade delivers the first and only air spring system to really come indistinguishably close to the linear spring rate of a coil fork for the entire first 2/3rds of its travel, with the advantage of a gentle end stroke progression to prevent bottoming without the “wall of force” harshness that excessively progressive springs create.

Key Features
  • Superior small bump compliance from the enlarged negative chamber
  • Experience enhanced support and predictability with our proprietary Midstroke Support Valve
  • Coil-like plushness and predictability, with air spring bottomlessness
  • Enables full use of travel in both directions
  • Enhances lubrication with increased lower leg oil volume
  • Lightweight at just 130g
  • Effortless setup -add air, bounce on it, press MSV charge button, ride
  • Compatible with OEM volume spacers
  • More consistent spring rate
  • Transfer between compatible forks with just a footstud change
